Given the assertion failure is "assert type(weight) == int"
22000:4fc66044477d looks a bit suspicious to me.
My guess would be that whatever writes cfg["vcpus_params"]["weight"]
before the patched code is writing something other than an int and that
this changeset means we no longer overwrite it with an int. I'm not
familiar enough with xend to say where that original write is happening
though.
